I replaced the igniter and the igniter relay. Still upon starting the ignition system does not attempt to work.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 05-19-2009 01:46 PM                     Replace the auto ignitor board..and also check that the rectifier is outputtting enough open-circuit voltage. Actually check the open circuit voltage first (should be in excess of 90-120 volts DC) and if that's low, the rectifier has issues.  |  IP: Logged Thomas Moore Film Handler Posts: 56 From: Imperial, Mo USA Registered: Oct 2005 posted 05-19-2009 02:24 PM                        Sorry but do i test where the 2 main wires run up to the lamp? thanks  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 05-19-2009 08:26 PM                     Anywhere you want. Usually it is easiest at the rectifier end. Just make sure the lamp does not attempt to strike while your meter is connected -- the high voltage spike can (and will) fry the meter. --jhawk  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

The amp meter should have a button next to it where it says "press for volts" or something similar. The lamphouses also have a trimpot which can be adjusted to trigger the igniter at various voltages. Sometimes all it takes is to turn the trimpot slightly clockwise and the igniter will be triggered much earlier. There is also a protective circuit with a reset button which sometimes pops out.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 05-20-2009 08:29 PM                     Since it will only light with the projector running I bet someone wired the 120 to the ignitor from the projector motor circuit  |  IP: Logged Aaron Sisemore Flaming Ribs beat Reeses Peanut Butter Cups any day!
